A simple simulation model for determining of thermal stress in cylindrical shell on the temperature gradient across the thickness of the walls

The condition of equality of distortions on the inner and outer surfaces of the walls of the shell is taken as the basis of simulation model. In contrast to the existing methods of calculation of thermal stress, the use of the suggested model excludes the calculation of the bending of a design element due to the temperature drop over the thickness of its walls and the reaction moment which makes calculations easier.
